Out of all my Chloe shoes the boots by far are a dream to wear. The shoes are a bit more challenging at first. Yoox has the chunky gold tone heeled sandal that has the cross over leather straps. I bought them a half a size larger and they were fabulous from the get go.
My Paddington sandals (also from Yoox) fits tts, however they cut into my toes. They get better with each wear. My mules were a dream from the get go, but the cross over wedges took allot of wear before comfort was experienced.
I do not have a pair of pumps. My guess is that they'll feel good up front, especially if the leather is on the soft side. If there is no platform and the heels are 4 inches or taller, I would recommend a half size larger than what you normally wear.
